How Much More Doa Informationin Higher - Order Statistics ?

چکیده
We consider the use of 2nd-and 4th-order cumulants for estimating the direction-of-arrival (DOAs) in narrow band array processing. The Fisher information about the DOAs contained in several cumulant statistics is computed. Numerical evaluation of the related Cram er-Rao bound is then used to point out, in this limited study, some advantages and drawbacks of using higher-order statistics.

QRC-ESPRIT Method for Wideband Signals
In this paper, a new algorithm for a high resolution Direction Of Arrival (DOA) estimation method for multiple wideband signals is proposed. The proposed method proceeds in two steps. In the first step, the received signals data is decomposed in a Toeplitz form using the first-order statistics. In the second step, The QR decomposition is applied on the constructed Toeplitz matrix. Compared with...
متن کاملDirection of Arrival Estimation Based on Fourth-order Cumulant Using Propagator Method
In this paper direction-of-arrival estimation (DOA) of multiple narrow-band sources, based on higher-order statistics using propagator, is presented. This technique uses fourth-order cumulants of the received array data instead of second-order statistics (autocovariance) and then the so-called propagator approach is used to estimate the DOA of the sources. The propagator is a linear operator wh...
متن کاملIcassp 92 DIRECTION FINDING ALGORITHMS USING FOURTH ORDER STATISTICS. ASYMPTOTIC PERFORMANCE ANALYSIS
This communication deals with high-resolution direction finding using higher-order cumulants of the array data. Two 4th-order cumulant-based matrices are considered : the diagonal cumulant slice and the contracted quadricovariance. They are evaluated in the context of DOA estimation using "subspace" techniques. To this purpose, we introduce an original methodology to derive the closed form of a...
متن کاملUnderdetermined DOA Estimation by the Non-Linear MUSIC Exploiting Higher-Order Moments
This paper describes a new approach for extending MUltiple SIgnal Classification (MUSIC) to underdetermined direction-of-arrival (DOA) estimation with high resolution by exploiting higher-order moments. The proposed method maps the observed signals nonlinearly onto a space of expanded dimensions, in which signal statistics are analyzed. The covariance matrix in the higher-dimensional space corr...
